To all whom it may, concern Be it known that I. ALVIN Butt, :1 citizenof the United States, residing at Nicholson, in the county of 'W omingand State of Pennsylvania, have invented certain newand.UsefulImprovements iii Devicesfoir Operating Dumping-Buokets, ofwhich the following is a. specification, refrsnce being had therein tothe accompanying drawing.

My invention refers to it clumping devise for buckets, more particularlylargo buckets designed to contain lair-53o qimntities of saith, clay,broken stone or other n'iaterial.

The objectof the invention is tosmibls tho buckets or receptacles ofthis kind to disoharg'etlisir contents with the eiqpEnditm-o of aslittle power as possible and by a simple and efficient trip meclizmism.which is easily and quickly operated.

Tho invention, therefore, consists essontially in the construction.:ii'1"m1gemm1t and combination of the various. parts, siibstztrr tiallywill loo hereinafter (lesoribocl and then more particularly pointed outin this claims.

Ellins tho-pin can OPCNI3Y= lit oi o tannin-it i, "he 'l'ectis in. itsop as this is the important object of the invention, and it is necessarythat 'it should be accomplished by mechanism whose details are simpleand yet effective. To this end I employ a trip lever which is pivoted at22 to the side of the notched projection -17. The trip lever 21, at itspivoted end, is formed with a rounded enlargement which is notched at 23for the purpose of receiving the bolt in said notch. These particularfeatures are indicated in Fig. 1 where it is seen that the pin or bolt20, when it lies in the notch 18 in the projection 17, will also beengaged by the notch 23 in the pivoted end of the lever 21. The form ofthe notch 23 as also the form of the pivoted end 21 may vary withinconsiderable limits. It is important that this lever 21 should have onthe other side of its pivot 22 a short projection which can rest beneaththe pin 20, so that when the free end of the lever 21 is pulled down,the pin 20 will be raised and lifted out of the notch 18 for thepurposes of setting free the locking bar 14 of the latch 11, and it isalso important that the notch 23 should look the pin 20 until it is timeto dump the bucket. A spring 24 is attached to the lever 21 and also tothe hook bar 1, or to one of the clamps 6, and serves to hold the lever21 in its upper position, as shown in Fig. 1, and to return it to thatposition after a releasing of the parts has been effected at eachdumping operation, so that the spring thus keeps the lever 21 and itsnotched end 23 in position to allow a locking engagement of the notchwith the pin 20 to be easily made from time to time. It is desirablethat the notch 23 should be employed rather than merely a short end ofthe lever 21 beyond the pivot, because the notch furnishe's an innerwall that will bear against the pin 20 as the spring pulls up the lever21 and will thus keep the one side of the notch in proper position underthe pin 20 at all times when the parts are actively related for service.The cable or cord 25,

which is attached to the outer end of the trip bar 21, may be anysuitable kind of a rope,-cable or cord running to some point where itcan be easily operated, and it will be found that only a slightexpenditure of power will be necessary to actuate the trippersufiiciently to disengage the pin 20 from the notch 18.

. The form of bucket with which my improved r elease device is generallyused is preferably of a formhaving two bails at the top and twin doorsopening at the bottom.

One of the bails is like that shown at 26 which is attached to the topof the bucket 1 and is permanently engaged by the hook 2. The other bail3, which rests on the latch arm 13 when the bucket is being loaded andcarried, is connected by suitable levers 27. as shown, to the doors 28at the bottom of the bucket. Obviously when the' bail 3 is released, theweight inside of the bucket will pull down thebail through the saidlevers, and the doors will automatically open and discharge the contentsof the bucket. The parts can all be reset for another filling of thebucket simply lifting the bail and placing it again upon the latch arm13, after the locking arm 14 has been locked in place by the pin 20 andthe tripper 21 set in place for further action in' dumping whenrequired.

Many changes in the precise construction and arrangement of the variousparts may be made without exceeding the invention, and I reserve theliberty of making all such changes as may in. practice be founddesirable or necessary.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:

1. In a device of the character described, the combination with a buckethaving doors and a hook for supporting said bucket, of a. pivoted latchfor the bucketdoors, said latch having a locking arm and also abucket-engaging arm, means for restraining said locking arm when thelatch is in its operative position, consisting of a swivel device and apin pivoted thereto so as to be adjustable in two directions, and meansfor releasing said pin consisting of a pivoted trip lever engaging thepin.

3. In a releasing device of the character described, the combination ofa bucket having dumping doors and a hook for supporting said bucket, abail connected with the dumping doors of the bucket. a pivoted latchengaging said bail, said latch having also a locking arm, a swivel bolt,a pin pivoted to said swivel bolt for holding the locking arm inposition when the latch keeps the dumping doors closed, and a trip leverengaging the pin.

4. In a releasing device of the class described, the combination of ahook bar. a companion latch-supporting bar, means for securing the twobars together, a latch pivoted to the latch-supporting bar and having abucket-engaging arm and also a locking arm, a pin pivoted to a swiveldevice so as to be adjustable in two directions, said pin niaaeeaserving to lock the latch arm, and means for releasing said pin,consisting oi a pivoted trip lever engaging the pin, together with a Ispring for returning the tripper after each tripping action.- p a 5. Ina device of the character described, the combination of a hook bar, alatch-supp rting bar, means for securing the bars together, a latchpivoted to the latch-support ing bar and having a bucket-engaging arm.and also alocking arm, a swivel device, a pin pivoted thereto, and meansfor releasing said pin consisting of a notched trip lever pivotedadjacent to saidpin.

6. In a device of the character described, the combination with a buckethaving a fixed bail and also dumping doors to which a movable bail isconnected, means for supporting the fixed bail, a latch device pivotedto said means and having an arm engaging the movable bail and also alocking arm, means for restraining said locking arm when the dumpingdoors are closed, said means comprising a swivel pin. and a pin pivotedthereto so as to be adjustable in two directions, together with meansfor releasing the latter pin, consisting of a pivoted trip leverengaging the pin.

In a release device of the character described, the combination of ahook bar, a pivoted latch having a bucket engaging arm and also alocking arm, a swivel device, a pin pivoted to said swivel device so asto be adjustable in two directions, and a notched and pivoted lever forengaging and releasing said pin.

8. In combination with a dumping bucket having a fixed bail, dumpingdoors and a movable 'bail connected to said doors, of means for engagingthe fixed bail and supporting the bucket, and a pivoted latch 'engagingthe movable bail, together with means for tripping said latch comprisinga swivel pin, a pin pivoted thereto so as to be adjustable in twodirections, and a notched trip lever engaging said pin.
